Surveillance By Flying Saucer

A flying saucer surveillance drone has been created by a British start-up company. Aesir has a prototype called Embler" that uses the "Coandă effect" which supposedly provides better lift for the device.

Take a look at the well-controlled flying saucer drone in the video below.

The Coandă effect was first demonstrated in aircraft by Henri Coandă in 1910. The effect can be described as the tendency of a jet of air (or more dense fluid) to stay attached to a close-by curved surface that is appropriately shaped

This flying saucer from Aesir looks a lot more cool than the ceiling fan hovering drone in Michael Crichton's 1985 movie Runaway.

Update 30-Jul-09: Take a look at this picture of the drones from the recent Dark Angel series starring Jessica Alba. The drones were played an especially important role in one episode - they had been modified to assassinate. Throughout the series, Jessica (Max in-story) had to dodge the drones so as to not be detected.
